Two computerized axial tomographic sections, one taken just below the coracoid process and the other about 2.5 cm proximal to the interepicondylar line, were used to determine glenoid version and humeral torsion in 19 patients with recurrent anterior glenohumeral joint dislocation and in 23 controls. Analysis of interobserver variation revealed the method to be reliable. There was no difference in glenoid version between the two groups. However, humeral torsion was greater in patients (153 degrees) than in controls (144 degrees). It appears that increased humeral torsion may predispose to glenohumeral joint dislocation.
对19例复发性前盂肱关节脱位患者和23例对照者，采用两张计算机断层扫描图像，一张在喙突下方水平，另一张在髁间线近端约2.5厘米处，以确定关节盂形态和肱骨扭转情况。观察者间变异分析显示该方法可靠。两组间关节盂形态无差异。然而，患者的肱骨扭转角度（153度）大于对照组（144度）。肱骨扭转增加似乎易导致盂肱关节脱位。
